Best Lysine-Rich Foods for Guinea Pigs
Ranked by lysine content among foods safe for guinea pigs in the Creature Feast catalog.
#1
Timothy Hayper 100g dry: ~0.3-0.4g lysine (lower than alfalfa's ~0.7g)Timothy hay provides lysine but at relatively low concentrations compared to legume hays like alfalfa. For adult guinea pigs, timothy hay's lysine is adequate when supplemented by quality pellets and varied vegetables. Growing guinea pigs and pregnant sows may benefit from alfalfa hay's higher lysine content during those life stages.
#2
Peasper 100g: ~0.32g lysinePeas are one of the richest plant sources of lysine available to guinea pigs. This makes them a valuable occasional treat — a few fresh or thawed peas provide a meaningful lysine boost that complements timothy hay's lower levels. Keep portions small due to starch content.
#3
Parsleyper 100g raw: ~0.19g lysineParsley provides modest lysine alongside its outstanding folate and Vitamin C content. A daily sprig contributes to the amino acid mix while supporting multiple nutrient needs. Parsley's protein is relatively lysine-rich compared to other herbs.
#4
Broccoliper 100g raw: ~0.14g lysineBroccoli provides moderate lysine as part of its broad amino acid profile. A small floret several times per week contributes to overall protein quality alongside its vitamins and fiber.
